Customer Complaint Management

Hi - seeking guidance from those whom may have implemented this, or have a solution:

  1. What is the best way to link/upload documents to Sage CRM when you receive a customer complaint?
  2. Or do you have to design a process workflow that allows you to add it on upon request?
  3. Has anyone been able to design a report that shows they type of complaints received, product description, resolution etc?

Thanks in advance.
